Why this level
- vcexecutecode runs arbitrary 1C code in the base
- vcexecutequery runs arbitrary queries, including potentially heavy ones
Install

Manual install
Open a 1C base with the MCP Server Constructor installed, load ИнструментыДляРазработки.xml through the standard data-load mechanism, and the tools will appear for the connected AI agent.
Access and checks
How we reviewBroad accessThe tool can change data, run commands or handle secrets.
- vcexecutecode runs arbitrary 1C code in the base
- vcexecutequery runs arbitrary queries, including potentially heavy ones
This is third-party code. Review the repository files before installing.
What it does
The repository is a single XML export of the APA_Инструменты catalog with four tools for the 1C MCP Server Constructor product: vcexecutecode runs arbitrary code in the built-in 1C language and returns the result or an error, vcexecutequery runs a query and returns a text table, validatequery checks a query's syntax without running it, and vcloggetlasterror returns the last error from the event log over 24 hours. After loading the XML into a base with the Constructor installed, the tools become available to connected AI agents as MCP tools.
Who it is for. For those already using the 1C MCP Server Constructor from the same author who want to add developer tools to the agent: code and query execution and error diagnostics.
Good fit when
- The 1C MCP Server Constructor from vibecoding1c.ru is already installed in the base
- You want an agent to run and validate 1C query-language queries directly in the base
- You need quick agent access to the last error from the event log
Not a fit when
- The MCP Server Constructor is not installed: there is nowhere to load the XML without it
- The base is production and strict rights limits matter: vcexecutecode runs arbitrary code
Example request

The tools only work inside the third-party 1C MCP Server Constructor product (vibecoding1c.ru), which is not distributed through this repository and is not open source. No license is specified, the tools are provided as is. The README explicitly warns that vcexecutecode and vcexecutequery run arbitrary code and queries in the base.
How to disable. Remove the loaded APA_Инструменты catalog items from the base, or disable the MCP Server Constructor entirely.
FAQ
Do these tools need a separate MCP server?
No, they are loaded as data into the already installed third-party 1C MCP Server Constructor, which exposes them over MCP itself.
Can vcexecutecode damage data?
Yes, it runs arbitrary 1C code, so the README advises using the tools only in a trusted environment with limited rights.

README in short
The README describes the XML export's four tools, requirements (1C platform 8.3 and the MCP Server Constructor installed), the data-load steps, call examples for each tool with sample responses, and a separate security section warning about arbitrary code execution.
